Using the knowledge in computational language in C++ it is possible to write a code that write a function so that the given string s consisting of n characters returns any string
Writting in C++ code:
#include <iostream>
#include <string>
using namespace std;
string solution(string &s)
{
//length of string
int n=s.size();
//index of string
int i=0;
while(i<n-1)
{
if(s[i]=='A')
{
if(s[i+1]=='B')
{
s=s.substr(0,i) + s.substr(i+2); i=0;
}
else
i++;
}
else if(s[i]=='B')
{
if(s[i+1]=='A')
{
s=s.substr(0,i) + s.substr(i+2); i=0;
}
else
i++;
}
else if(s[i]=='C')
{
if(s[i+1]=='D')
{
s=s.substr(0,i) + s.substr(i+2);
i=0;
}
else
i++;
}
else if(s[i]=='D')
{
if(s[i+1]=='C')
{
s=s.substr(0,i) + s.substr(i+2);
i=0;
} else
i++;
}
n=s.size();
}
return s;
}
int main() {
//Input string
string s="ACBDACBD";
solution(s);
//final output;
if(s=="")
cout<<"Empty String";
else
cout<<s;
return 0;
}
